QTP® 2645 — heat- and chemical-resistant polyurethane-cement

Polyurethane-cement floors

This version of the QTP 2640 polyurethane-cement has the same field of application: priming, levelling, self-levelling, highly filled and paint finish coatings. It withstands up to +130 °C continuously and up to +150 °C for up to 12 h, and is resistant to most chemicals. Foot traffic is possible after 6 h at +20 °C; full strength develops in 21 days. Compressive strength is 65 MPa and adhesion to concrete more than 3 MPa.
